When temperatures soar across North Carolina, South Carolina, and South Central Virginia, the climate doesn’t just affect people—it impacts your building materials, too.
At Seven Oaks Commercial Doors and Hardware, we’ve seen how hot and humid or hot and dry weather can wreak havoc on commercial and industrial doors, especially in sectors that rely on year-round durability and compliance.
Whether your facility operates in manufacturing, healthcare, education, retail, or industrial warehousing, climate-related stress on doors can mean reduced performance, safety concerns, and higher maintenance costs. Let’s break down how the heat and humidity affect commercial doors—and how to choose materials and solutions that last.
Climate Impacts: What Happens to Doors in the Heat?
Hot and Humid Conditions (Typical in Coastal and Piedmont Areas of NC/SC/VA)
Humidity causes door materials—especially wood and lower-grade metals—to expand, swell, or even warp. This can result in:
-
Misaligned frames
-
Sticking doors
-
Difficulty closing or latching
-
Reduced fire door integrity
These issues are especially problematic in sectors like healthcare and education, where code compliance and emergency egress are non-negotiable.
Hot and Dry Conditions (Common in Inland and Rural Regions)
On the flip side, extremely dry conditions, often found in rural or southern inland areas of VA and the Carolinas, can lead to:
-
Shrinkage and cracking of wood cores
-
Paint flaking and seal deterioration
-
Excessive dust exposure impacting door hardware and hinges
In facilities like distribution centers or light industrial plants, these seemingly small problems can halt operations, delay shipments, and compromise facility security.
Material Matters: What You Should Be Using
At Seven Oaks, we specialize in specifying and installing doors and frames built for the unique climate demands of the Carolinas and South Central Virginia.
1. Steel Doors with Thermal Breaks
These are ideal for areas with high humidity or fluctuating temperatures. Thermal break construction prevents condensation, resists rust, and maintains energy efficiency.
2. Fiberglass Reinforced Doors (FRP)
Perfect for healthcare or school buildings, FRP doors resist warping, bacteria growth, and require minimal maintenance—even in high-moisture or high-heat areas.
3. Stainless Steel Doors
In food processing plants, medical labs, or coastal regions, stainless steel doors are your best bet. They stand up to salt, humidity, and constant sanitation cycles.
4. Proper Weatherstripping and Seals
Often overlooked, high-quality seals and gasketing are essential. They help doors maintain their shape and function, even when the thermometer hits triple digits.
